Iran’s bitumen has one of the highest qualities in the world and at the present, Iran is the first exporter of bitumen in the Middle East and the fourth largest exporter in the world. This product has been exported to the Middle East, South and East Asia, Africa and Europe.
Bituminous is hydrocarbon material with high viscosity and colloidal structure, and black to dark brown color and is completely dissolved in carbon sulfide and carbon tetrachloride. Impenetrable to moisture and water, electrical insulation, elasticity, moderate persistent against acids, bases and salts and adhesion to other materials is the most important feature of Bitumen. The Most production of bitumen in the world, is petroleum bitumen or tar distillation which is obtained from crude oil distillation and they are classified based on the degree of influence (standard ASTM-D5). And also this group is able to supply all kinds of this product according to customer’s needs.
